Abstract: The Norfolk Harbor Study Area includes the ocean entrance channel, the inner harbor channels, and dredged material disposal sites. Alternative plans combined multiple structural and nonstructural measures to improve the safety and efficiency of the existing navigation system. Navigation concerns include three main types of problems: limited channel depth that causes navigation inefficiencies, channel width that does not allow safe meeting of vessels, and existing anchorages which are insufficient to fully accommodate the existing vessel fleet. The Preferred Alternative (also referred to as the Action Plan or Recommended Plan is the National Economic Development (NED) Plan which includes: • Deepening the Atlantic Ocean Channel (AOC) to a required depth of -59 feet; Deepening the Thimble Shoal Channel (TSC) to a required depth of -56 feet; • Deepening the Norfolk Harbor Channel to a required depth of -55 feet; • Deepening the Norfolk Harbor Entrance Channel to a required depth of -55 feet; • Deepening the Newport News Channel to a required depth of -55 feet; • Widening the TSC east of the Chesapeake Bay Bridge Tunnel to 1,300 feet; • Widening Anchorage F to 3,620 feet and associated modifications of the Approach Area; • Deepening Anchorage F to a required depth of -51 feet; The Preferred Alternative includes construction and maintenance of these features. Dredged material placement/disposal could occur at the Dam Neck Ocean Disposal Site, the Norfolk Ocean Disposal Site, the Craney Island Dredged Material Management Area (CIDMMA), and/or upland disposal sites for this project (if needed). Portions of the dredged areas may be suitable for beneficial use projects and beneficial use projects would be coordinated separately from this project. General operation and maintenance of the CIDMMA would continue with or without implementation of the Preferred Alternative. The project construction is anticipated to begin in approximately 2019 (or earlier depending on funding capability) and following construction, channel depths would be maintained over the 50 year lifecycle of the project.
